There's a code of conduct where the agent are suppose to provide all offers. Does he have too, not really. Can you sue him for it? Yes.
I've seen an agent did this once to his client. He had multiple offers, but only presented the one that he was representing both buyer and seller, so that he can double end the commission. Even though the other offer was slightly higher, he did not represent the buyer. Owner did not know about it.
